Smelling Fatty Foods in Pregnancy May Raise Obesity Risk in Children

New research shows that exposure to the smell of fatty foods during pregnancy and early life can reprogram the developing brain and increase the risk of obesity and insulin resistance in adulthood. Even when mothers consumed a healthy low-fat diet, the presence of fatty food odors altered how offspring responded to high-fat foods later.

Scientists Achieve Sustained HIV Control Without Lifelong Drugs

Scientists tested a multi-step immune-based therapy designed to retrain the body to control HIV without continuous antiviral treatment. After stopping standard HIV drugs, seven out of ten participants maintained low viral levels for extended periods, and one showed no viral rebound at all.

Insomnia Keeps the Brain Stuck in Daytime Mode

People with chronic insomnia show a delayed and weakened daily rhythm of mental activity, keeping the brain in a more alert, daytime-like state at night. Under tightly controlled conditions, individuals with insomnia failed to show the normal nighttime drop in goal-directed thinking seen in healthy sleepers.

The Way You Drive Might Signal Mild Cognitive Impairment

Researchers found that long-term driving behavior can reveal early signs of cognitive decline years before clinical diagnosis. Older adults who later developed impairment showed gradual reductions in trip frequency, night driving, and route variety compared to cognitively healthy peers.

Brain Damage in Schizophrenia May Begin in Specific Neural Epicenters

New brain imaging research shows that structural damage in schizophrenia spectrum disorders may begin in specific “epicenter” regions before spreading across connected brain networks. Individuals with the condition showed widespread reductions in structural similarity between key cognitive and emotional brain regions.

AI Uncovers Hidden Stress Damage in the Body

Researchers developed an AI tool that detects chronic stress by measuring adrenal gland volume on routine chest CT scans. This biomarker aligns with cortisol levels, stress questionnaires, and future cardiovascular outcomes, offering the first imaging-based method to quantify stress load in the body.

Young Adults With Obesity Show Early Signs of Brain Stress

New research shows that young adults with obesity already display biological patterns associated with liver stress, chronic inflammation, and early neural injury—changes typically seen in older adults with cognitive impairment. Participants with obesity also had unusually low blood choline levels, a nutrient critical for liver function, inflammation control, and long-term brain health.

Your Brain Has a Built-In Isolation Mode

New research uncovers the exact immune-to-brain pathway that drives the loss of social motivation during sickness. Scientists showed that when the cytokine IL-1β binds to receptors on neurons within the dorsal raphe nucleus, it activates a circuit that reduces social interaction.

Untreated Sleep Apnea Doubles Parkinson’s Risk

A large analysis of more than 11 million medical records found that people with untreated obstructive sleep apnea face a substantially higher risk of developing Parkinson’s disease over time. Even after accounting for factors like age, obesity, and cardiovascular conditions, those who did not use CPAP were nearly twice as likely to be diagnosed with Parkinson’s as those who treated their apnea.

Gene Discovery Reveals Hidden Risk Pathway for Delirium

A massive genetic analysis of over one million people has revealed that APOE, long known for its role in Alzheimer’s disease, also independently increases a person’s risk of delirium. The researchers found that this effect cannot be explained solely by dementia, showing that APOE directly contributes to delirium vulnerability in otherwise cognitively healthy individuals.

Genetics Point to a New Type of Suicide Risk

New research shows that many people who die by suicide without prior suicidal thoughts or behaviors are not simply “missed cases”—they may have an entirely different underlying risk profile. Genetic analyses of more than 2,700 deaths revealed that these individuals carry fewer genetic risk factors for major psychiatric conditions compared to those with known suicidality.

Stress-Like Behaviors Traced to a Single ATP Circuit in the Brain

New research reveals that reduced ATP signaling in the hippocampus plays a causal role in both depression- and anxiety-like behaviors. In stressed male mice, ATP levels and the ATP-releasing protein connexin 43 were markedly lower.
